The server rack according to the invention includes a frame thatincludes hollow tubular support posts on the front sides and rear sidesof the device. Between the front and rear posts are forward side panelsand rearward side panels. The panels receive a complement of cartridgesthat have valve members to control the flow of air from a rear cavitythough passages in the cartridges, through the rail and into servers. Aplurality of side rails for receiving servers are attached to the frontand rear posts. The rails have passages through the sidewalk thatcorrespond with passages provided on the sidewalls of the servers.

In a preferred embodiment, air conditioned air is introduced to forwardside panels through passages provided on the upper and lower surfaces.Next, air travels from the forward panel, though one or more passagesthat is provided through a cartridge member, and then, into a frontsection of a server through a passage that is provided on the lateralsidewall of the server. Air travels through the server from the frontsection of the server to a rear section and then exits through a passagein the lateral sidewall to a cartridge that is provided in a rear panel.Next the air is returned to the air conditioner unit for recirculation.

In an embodiment the sever rack is approximately 6 feet tall anddesigned to accommodate forty-two server units in 4.445 cm (1.75 inch)increments. Rail members are provided at each unit segment on the sidepanels and support a server. In embodiments further discussed below,passages through the cartridges have at least one valve member that canbe individually electromechanically or manually controlled. When noserver is provided in a specific rack unit, or when the temperature isotherwise adequately controlled in a particular server unit, theaperture may be closed. In embodiments, a controller automatically opensor closes valve members provide in cartridges in response to a signalfrom a thermometer.

As such, it should be appreciated that the valves or passages can beopened and closed variably for each server depending on the coolingneeds for the server. Further, as discussed herein, the degree of airflow through the aperture can be controlled using a damper or weirarrangement. Therefore, in embodiments, a local controller is providedand can receive input information from thermometers reading thetemperatures of the servers and can adjust the opening and closingvalves aperture accordingly. Alternatively the dampers may be manuallyadjusted. In yet further embodiments a central controller receivessignals from a plurality of server racks.

Each of the openings on the post is provided with a releasable seal toblock flow depending on the particular configuration of servers. Inembodiments, flexible manifolds extend from the posts to direct thefluid to and from access areas provided on the servers. While thepreferred embodiment contemplates the use of air flow, in embodimentsthe frame is configured to receive a liquid and the posts and manifolddirect fluid to heat exchange elements that engaged the respectiveservers.

In yet further embodiments the rack is configured to allow both liquidflow and air flow.
